I think you'd use the pythagoran theorem for this (a squared + b squared = c squared). So 30 squared plus 22 squared equals the diagonal measure squared. This is 900 + 484 = c squared. That's 1384. The square root of that is 37.
Ok so you have to use PEMDAS . so first you have to get rid of the parenthesis.
2 x 6x = 12x then 2 x -5= -10
12 + 5x -8 = 12x -10
combine now: 12 - 8 = 4
5x + 4 = 12x - 10
- 4 -4
5x = 12x -14
-12x=-12x
-7x = -14
-14/-7
x=2

Answer:
D.) 38.6 m
Step-by-step explanation:
Use the cosine ratio:

Because we are given the measure of an angle and the length next to it (adjacent), and we need to find the hypotenuse (the hypotenuse is NEVER considered the adjacent side). Insert the values:

Now isolate the variable. Multiply both sides by x:

The x's on the right side cancel each other out. Simplify:

Now divide both sides by cos75°:

The cos75° on the left side cancels each other. Simplify:

Insert this value into a calculator to simplify the value of x:

The hypotenuse is 38.6 m.
